Aston Martin’s new GT, the One-77, seems to be an exercise in pushing the Aston brand even further toward the stratosphere. The idea behind the One-77 is to offer a personally tailored car to 77 wealthy customers prepared to part with as much as $2.5 million. Fundamentally, the One-77 is similar to its lesser kin, the DB9 and the Vanquish, but the V-12 engine has been enlarged to 7.0 liters and turns out 650 horsepower. The aluminum structure is replaced with a carbon-fiber composite hull, and the body is clothed in a new aluminum skin. Expect a show car next year that also will be shown to 500 potential customers that Aston has identified. It seems this ultra-exclusive Aston is not the rumored “DBX” replacement for the Vanquish, though some of the technology from the One-77 may find its way into that car.
